**Nasdaq's 13-day winning streak ends.**

The decline was smaller than expected (-0.5%~-1.5%)—the reason was Iran's statement that day expressing willingness to participate in a second round of negotiations, partially hedging panic sentiment. Geopolitical risks remain, but market resilience exceeded expectations.

## Why ARM Surged Against the Trend

Two research reports released on the same day created a combined effect:

-   **Susquehanna**: Sustained data center demand continues to drive semiconductor upside, ARM will continue to increase its CPU market share among hyperscale cloud providers.  
    
-   **Bank of America**: Raised the server CPU industry CAGR forecast to 15%, raised ARM's price target from $155 to $180.  
    

Underlying logic: In the AI Agentic era, the CPU:GPU ratio narrows from 1:8 to 1:1, with ARM architecture being the biggest beneficiary.

## My Trades

This time, I bought QQQ according to the monthly DCA plan, switching to execution after the day session opens (previously it was always the night session). Bought below the day's closing price, execution quality is satisfactory.

Persisted in executing DCA amidst geopolitical risks because: **Buying on down days is precisely the advantage of DCA; over a 10-year horizon, today's price difference is almost negligible.**

## Tonight's Focus: TSLA Earnings

**Tesla releases Q1 earnings tonight**, market expectations are conservative (Q1 delivery miss is already consensus).

Key things to watch:  
\- FSD / Robotaxi commercialization progress  
\- Whether Musk gives strong guidance  
\- Energy business growth

If guidance exceeds expectations → possible significant rebound; if continues to disappoint → selling pressure persists.

The ceasefire agreement expires today, Iran negotiation progress remains the macro main theme, continue to monitor.
